The B-Pipe has an additional O2 bung that you will not use. I searched and searched for a solution and was unable to find one here on the boards. I figured I'd share how I fixed it.

After going to three home depot's, two ace hardware's and a Lee Auto parts, I still couldn't find the correct size bolt or O2 plug anywhere. The size you need is 18mm I believe.

I finally went to Murray's and spent 45 minutes scouring the store head to toe until I figured something out. There is a commonly available Ford sparkplug for a 94 F150 that fits perfectly. The P/N is SP-452 or BSF44P. The part is $2.50 and makes a perfect seal.

 

lol so you put a spart plug in your b-pipe. I gotta say that is amazingly creative way of thinking. w/e works i guess.

 

man, you're shadowing me on both forums...

yeah it was the only thing i could find to fill my empty bung
